I need advice on attending first stage in oracle

Question

I want to follow a carrier in this and need help and avice on were to start and how to please

Answer 1

I have been an Oracle Database instructor on Linux platform since 2008.

By first stage you meant OCA (Oracle Certified Associate).

If I were to train you I would first start with Linux O.S, next to SQL (Structured Query Language), finally OCA.

All my training books are written by me from different sources.

So tell me if you need self training or private, am from Nigeria.
